Free online tools for text, numbers, images and PDFs

ToolsWish groups 171 tools into eleven categories, and every one of them works the same way: paste or drop something in, see the result straight away, copy it out. Case converters fix capitalisation. Fancy text generators turn plain words into bold, italic, bubble or glitch text for social media bios and captions. Cleanup tools strip line breaks, duplicate lines, extra spaces and leftover formatting. Encoders and ciphers handle Base64, binary, hex, Morse code and ROT13.

Calculators answer money and health questions: loan EMI, mortgage payments, compound interest, percentages, BMI, calories and ages. Unit converters show length, weight, temperature, speed and data size in every unit at once. Image and PDF tools compress, resize, crop and convert images, build favicons, read text from pictures and merge, split, rotate or convert PDFs without uploading them. Developer tools format JSON, convert CSV, test regular expressions, decode JWTs and build UTM links, while the random generators, counters and everyday tools cover QR codes, placeholder text, random picks and a typing test.

1. Paste or type your text into the box above. Word, character and line counts update as you type.
2. Click the case you want: Sentence case, lower case, UPPER CASE, Capitalized Case, Title Case, aLtErNaTiNg cAsE or InVeRsE CaSe.
3. The text in the box changes immediately. Click another case to try a different style on the same text.
4. Press Copy to put the result on your clipboard, or Download to save it as a .txt file.

Nothing is uploaded. The conversion runs in your browser, so the tool is safe to use with drafts, emails and documents you would rather keep private.

• Sentence case capitalises the first letter of each sentence and lowercases the rest, which is how normal prose is written. Example: This is sentence case.
• lower case turns every letter into lowercase, useful for usernames, hashtags, email addresses and code. Example: this is lower case.
• UPPER CASE turns every letter into capitals for headings, labels and acronyms. Example: THIS IS UPPER CASE.
• Capitalized Case starts every word with a capital letter. Example: This Is Capitalized Case.
• Title Case capitalises the major words of a title and keeps small words such as "a", "of" and "the" lowercase. Example: This Is an Example of Title Case.
• aLtErNaTiNg cAsE swaps between lower and upper letters, the style used in sarcastic memes. Example: tHiS iS aLtErNaTiNg cAsE.
• InVeRsE CaSe flips the case of every letter, turning capitals into lowercase and lowercase into capitals.

Each case also has its own page with more options: sentence case, title case, upper case, lower case, capitalized case and alternating case.

Most online tools send your text or file to a server, process it there and send the result back. ToolsWish does the work on your own device instead. The page downloads a small script once, and from then on every conversion, calculation, image resize or PDF merge happens locally. That is why results appear as you type, why the tools keep working on a slow connection, and why nothing you paste is logged, stored or seen by anyone else. The only exception is the IP address tool, which has to read the address your connection presents, and even that is shown to you without being saved.

It also means the tools are safe to use with drafts, contracts, customer lists, passwords you are testing and files you would not want on a stranger's server. If you want to check, open the browser's network panel while you convert something: no request leaves the page. Read more on the privacy policy or the about page.
